Now even Nokia developer site has changed its specs sheet, should we assume that 630/635 have no proximity and ambient light sensor? Nokia, wasn't 512 MB ram and flash/front camera omission enough for you to cut costs? Nokia 630 is a joke without these two sensors. No double tap to wake up. Low brightness setting is not really low in windows phone. I solely rely on ambient light sensor at night. These should have been added, otherwise price should be dropped to such an extent that 630 justifies these omissions. Is a quad core processor as a upgrade alone enough ?
